Full title and description

ISO/TR 52018-2:2017 — Energy performance of buildings — Indicators for partial EPB requirements related to thermal energy balance and fabric features — Part 2: Explanation and justification of ISO 52018-1. This technical report provides background, explanation and justification for the indicator choices listed in ISO 52018-1; it is informative (non‑normative) and intended to support regulators, authorities and other stakeholders in selecting and reporting partial EPB requirements related to building thermal balance and fabric features.

Abstract

ISO/TR 52018-2:2017 refers to ISO 52018‑1 and expands on the rationale behind the overview of options given there. It provides background considerations, examples and reporting aids to help private actors and public authorities make informed decisions about partial energy‑performance requirements related to heating/cooling needs, thermal balance (including overheating/free‑floating temperatures) and fabric features. The report contains no normative requirements.

Scope

This technical report explains and justifies the indicator choices presented in ISO 52018‑1. Its scope is to provide background, interpretive guidance and reporting support for partial Energy Performance of Buildings (EPB) requirements that are specifically related to the building thermal energy balance (heating, cooling, overheating risk, free‑floating temperatures) and to fabric features (insulation, U‑values, thermal bridging aspects, etc.). The document is informative only and does not introduce normative requirements; instead it helps regulators and stakeholders to document, compare and select options from ISO 52018‑1 in a transparent and consistent way.

Key topics and requirements

• Explanation and justification of the indicator choices listed in ISO 52018‑1 (rationale and background considerations).
• Guidance on partial EPB indicators tied to thermal energy balance (heating/cooling needs, overheating risk, free‑floating temperature behaviour).
• Guidance on partial EPB indicators tied to fabric features (thermal performance of envelope elements, U‑values, thermal bridges, etc.).
• Non‑normative tables and reporting templates to record regulators’ choices in a uniform manner (supports transparency and comparison).
• Practical considerations for implementation and examples to assist policy makers, authorities and industry in selecting appropriate partial requirements.

Typical use and users

Primary users are national and regional regulators, building authorities and policy makers who design or adopt partial EPB requirements. Secondary users include energy consultants, building designers and engineers, certification bodies, academic researchers and industry stakeholders who need to understand the rationale behind indicator choices and how to report them consistently. The report is used when deciding which partial indicators to apply, documenting those choices, and communicating regulatory approaches in a transparent way.

Related standards

Directly related: ISO 52018‑1 (Part 1: Overview of options) — ISO/TR 52018‑2 provides the explanation and justification for the Part 1 options. The report also sits within the broader EPB modular family (for example ISO 52000‑1, ISO 52016‑1 and ISO 52017‑1 series that cover EPB concepts, calculation procedures and hourly/internal temperature methods). Users implementing partial requirements will commonly consult ISO 52018‑1 together with the core EPB calculation and assessment standards.

FAQ

Q: What is this standard?

A: ISO/TR 52018-2:2017 is an informative technical report that explains and justifies the indicator options listed in ISO 52018‑1 for partial EPB requirements related to building thermal balance and fabric features. It is not a normative standard; it provides background and guidance.

Q: What does it cover?

A: It covers explanation, justification and practical background for partial energy‑performance indicators related to heating and cooling needs, overheating/free‑floating temperatures and fabric characteristics (envelope thermal performance). It includes reporting aids to help regulators document their choices.

Q: Who typically uses it?

A: Regulators and public authorities setting EPB partial requirements; energy policy makers; energy consultants; building designers and engineers; certification Bodies and researchers who need context and rationale for indicator selection.

Q: Is it current or superseded?

A: As published it is an ISO Technical Report from 2017 (Edition 1, published June 2017). Users should check the ISO catalogue or their national standards body for any later revisions or confirmations; the TR itself is informative and accompanies ISO 52018‑1 (2017).

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 52018 series (Part 1 is ISO 52018‑1:2017). It also forms part of the wider ISO EPB (energy performance of buildings) modular set of standards (ISO 52000 series and related calculation method standards).

Q: What are the key keywords?

A: energy performance of buildings, EPB, indicators, partial requirements, thermal balance, fabric features, overheating, U‑value, thermal insulation, reporting.
